Rockitt Retro amplifiers...made to KICK ASS...!!!...because that is exactly how I build them. I am a life long guitar player with a passion for "vintage tube tone". I believe it to be the definitive sound of Rock-n-Roll...and for myself the Plexi is the perfect amp to achieve "that sound". All the greats have used them...and for good reason...it simply doesn't get any better...!!! Love and Volume!!! Kevrockitt
